.. _ceph-volume-lvm-create:
|
||
|
|
|
||
|
|
``create``
|
||
|
|
===========
|
||
|
|
This subcommand wraps the two-step process to provision a new osd (calling
|
||
|
|
``prepare`` first and then ``activate``) into a single
|
||
|
|
one. The reason to prefer ``prepare`` and then ``activate`` is to gradually
|
||
|
|
introduce new OSDs into a cluster, and avoiding large amounts of data being
|
||
|
|
rebalanced.
|
||
|
|
|
||
|
|
The single-call process unifies exactly what :ref:`ceph-volume-lvm-prepare` and
|
||
|
|
:ref:`ceph-volume-lvm-activate` do, with the convenience of doing it all at
|
||
|
|
once.
|
||
|
|
|
||
|
|
There is nothing different to the process except the OSD will become up and in
|
||
|
|
immediately after completion.
|
||
|
|
|
||
|
|
Although initially :term:`filestore` is supported (and supported by default)
|
||
|
|
the back end can be specified with:
|
||
|
|
|
||
|
|
* :ref:`--filestore <ceph-volume-lvm-prepare_filestore>`
|
||
|
|
* ``--bluestore``
|
||
|
|
|
||
|
|
.. when available, this will need to be updated to:
|
||
|
|
.. * :ref:`--bluestore <ceph-volume-create_bluestore>`
|
||
|
|
|
||
|
|
All command line flags and options are the same as ``ceph-volume lvm prepare``.
|
||
|
|
Please refer to :ref:`ceph-volume-lvm-prepare` for details.
